关于mvc微信公众号支付源码的信息
一mvc微信公众号支付源码：简介
手机网站支付常用于HTML5应用，常见于微信公众号上的应用。手机网站支付文档
手机网站支付的流程图：
用户点击H5应用中的支付按钮点击支付按钮会请求后台接口，后台接口请求支付宝的支付接口，支付接口会返回一段html代码其中包括一个form表单和一段js代码用于自动提交表单，表单提交后就会自动跳转到支付宝的支付页面(如果手机中装了支付App就去打开APP，如果没有就在网页版支付支付成功后会调用支付时设置的同步url, 然后跳转到商户的后台系统，一般情况下商户系统会展示一下支付成功，以及购买的商品信息等视图流程图
二：集成步骤0. 创建应用、配置密钥集成前需要先创建应用、配置密钥、回调地址等，具体操作请查看Spring Boot入门教程(三十五):支付宝集成-准备工作
